The aim of the study is to evaluate the role of the Grand fir (Abies grandis [Dougl. ex D. Don] Lindl.) as a soil-improving species in the area of the University Training Forest in Kostelec nad Černými lesy, Jevany district. The state of humus forms in the stand part with Grand fir was compared with the mature Norway spruce (Picea abies [L.] Karst.) without regeneration, with young beech (Fagus sylvatica L.), Norway spruce (Picea abies [L.] Karst.) and oak (Quercus spp. L.) stands (all of pole stage). The site is characterized as 4P1 - acid oak-fir site with Luzula pilosa, the geological bedrock is formed of...

Top-soil samples were taken from four mountain forest ecosystems in the Bohemian Forest to compare the processes in European beech-mixture (Fs) and Norway spruce (Pa) dominating ecosystems. Selected plots can be grouped into two types of forest ecosystems which are conditioned by position on the natural altitudinal gradient. Several chemical features (content of organic matter, properties of humic and fulvic acids, releasable P, Ca, Mg, Fe and Al content) were compared with the species structure of oribatid mite communities in the same samples. Strict differences between both ecosystem types were discovered. Statistically significant...
Differences in fine root traits between Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica L.) - A case study in the Kysucké Beskydy Mts

Interspecific comparisons of the fine root "behaviour" under stressful situations may answer questions related to resistance to changing environmental conditions in the particular tree species. Our study was focused on Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica L.) grown in an acidic soil where acidity was caused by past air pollution in the Kysucké Beskydy Mts., North-Western Slovakia. Between April and October 2006, the following fine root traits were studied: biomass and necromass seasonal dynamics, vertical distribution, production, mortality, fine root turnover and production to mortality ratio. Sequential...
Changes of the mixed mountain virgin forest after 70 years on a permanent plot in the Ukrainian Carpathians 567

During 2004-2006, another permanent research plot (No. 12) on Pop Ivan Marmarosh Mt. in the Zakarpattya province of Ukraine was renewed, i.e. re-measured and re-analyzed. The plot was originally established in the 30's of the 20th century. The tree layer is dominated by European beech (Fagus sylvatica L.), with Silver fir (Abies alba Mill.) and Norway spruce (Picea abies [L.] Karst.) as often associated species, and with sycamore maple (Acer pseudoplatanus L.) growing occasionally in small groups. After 70 years, the tree species composition partly changed. Total live timber volume increased from 529.6 to 636.3...
How do lepidopteran seasonal guilds differ on some oaks (Quercus spp.) - A case study

The differences between oak lepidopteran communities were studied in Slovakia in 1993 and 1994. Sampling was undertaken between April and October on 3 oak species (Quercus robur, Q. petraea, Q. rubra). Biological traits of larvae were examined in order to explain differences in seasonal guilds among oaks. Communities varied in structure and abundance. Species richness in four seasonal guilds (flush, late spring, summer and autumn feeders) had a similar pattern on each of the studied oak species. The guild of flush feeders had the richest species assemblage, followed by the late spring feeder guild and both guilds were significantly richer than...
